Reports from seismologists and seismological organizations indicate that up to 3,000 fatalities may have occurred in northwest Iran and southeast Turkey.
In the early morning hours of August 16, 1931, a powerful earthquake occurred in West Texas with a maximum Mercalli intensity of VIII (Severe). Estimates of its magnitude range between 5.8 and 6.4 mb, making it the most powerful earthquake ever recorded in Texas history. Its epicenter was near the town of Valentine, Texas; there, the earthquake caused damage to many homes and buildings. The earthquake may have been caused by movement along oblique-slip faulting in West Texas, the most seismically active region in the state. Shaking from the earthquake was perceptible within a 400 mi (640 km) radius of the epicenter, affecting four U.S. states and northern Mexico. Several foreshocks and aftershocks accompanied the primary temblor, with the aftershocks continuing until at least November 3, 1931. The main earthquake caused no fatalities, though several people sustained minor injuries; the damage in Valentine amounted to $50,000–$75,000.
The 1893 Quchan earthquake occurred at about 19:30 local time on 17 November. It had an estimated magnitude of 6.6 on the surface-wave magnitude scale and a maximum perceived intensity of IX (Violent) on the Mercalli intensity scale. It caused severe damage in Quchan County, particularly to the town of Quchan itself and there were an estimated 18,000 casualties.
The 2000 Tottori earthquake occurred on 6 October 2000, at with a moment magnitude of 6.7 and a maximum Mercalli intensity of VIII (Severe). The epicenter was near Yonago and Matsue. About $150 million in damage was caused and between 130 and 182 people were injured.

The 1979 Ghaenat earthquakes were a series of large earthquakes in Qaen County, Khorasan Province, northeast Iran, near the Afghanistan border. The first mainshock, known as the Korizan earthquake with a surface wave magnitude (Ms ) of 6.6 and moment magnitude (Mw ) of 6.8, struck on November 14, while the Ms 7.1 or Mw 7.2 Koli-Boniabad earthquake struck on November 27. The two mainshocks were assigned a maximum Modified Mercalli intensity of VIII (Severe) and X (Extreme), respectively. The earthquakes caused extensive damage throughout northeastern Iran, killing an estimated 297 to 440 people and left at least 279 injured.
The 1997 Bojnurd earthquake occurred on 4 February at 14:07 IRST in Iran. The epicenter of the 6.5 earthquake was in the Kopet Dag mountains of North Khorasan, near the Iran–Turkmenistan border, about 579 km (360 mi) northeast of Tehran. The earthquake is characterized by shallow strike-slip faulting in a zone of active faults. Seismic activity is present as the Kopet Dag is actively accommodating tectonics through faulting. The earthquake left 88 dead, 1,948 injured, and affected 173 villages, including four which were destroyed. Damage also occurred in Shirvan and Bojnord counties. The total cost of damage was estimated to be over US$ 30 million.
The 1977 Naghan earthquake struck Chaharmahal and Bakhtiari province in Iran on April 6 at 13:36 UTC. The earthquake measuring 6.0 Mw occurred at a depth of 15 km (9.3 mi) and had a maximum Modified Mercalli intensity of VIII (Severe). More than 2,100 homes were destroyed and at least 348 people died.
The 1957 Alborz earthquake struck northern Iran's Mazandaran province at 04:12 local time on 2 July. It had a moment magnitude (Mw ) of 7.1 and occurred at a focal depth of 15 km (9.3 mi). The thrust-faulting shock was assigned a maximum Modified Mercalli intensity of IX (Violent). It devastated 120 villages in the Alborz Mountains and caused an estimated 1,500 fatalities. The earthquake also triggered landslides including one that dammed the Haraz River. Some damage was also reported in Tehran, Qaem Shahr and Sari. The total damage was estimated at US$25 million.
The 1947 Dustabad earthquake, also known as the Charmeh earthquake, occurred in South Khorasan Province of northeastern Iran on 23 September. The mainshock had a magnitude of 6.9 and maximum Modified Mercalli intensity of VIII (Severe). It was accompanied by a Mw 6.1 aftershock on 26 September. These earthquakes killed an estimated 500 people.
The 1871–72 Quchan earthquakes which affected present-day Razavi Khorasan province occurred less than a month apart. The first earthquake, measuring 7.1, occurred on 23 December 1871, was followed by a Mw 7.0 earthquake in the same area on 6 January 1872. Altogether, these earthquakes killed at least 6,000 people in the Quchan area.
